$(eval) does not work

[Egil Moeller]

$(eval) can not currently be used to define new rules (and actually
makes make core-dump) and thus I need help to solve the following
problem:

I need to have a work-alike to what this Makefile intends to do (but
does not as eval does not work):

-----{Makefile}-----
#### Dependencies ####

.PHONY: %.deps
%.deps: %.mk
        $(eval include $<)

#### Images ####

%.pnm: %.jpg
        jpegtopnm $< > $@

%.tiff: %.pnm
        pnmtotiff $< > $@

%.eps: %.tiff %.size
        tiff2ps -e -3 $< > $@

#### Texts ####

%.texml: %.xml %.texml.deps
        xsltproc poetry.texml.xsl $< > $@

%.texml.mk: %.xml
        xsltproc --stringparam filename $* poetry.texml.deps.xsl $< > $@

%.latex: %.texml
        texml $< $@

%.html: %.xml %.html.deps
        xsltproc poetry.html.xsl $< > $@

%.html.mk: %.xml
        xsltproc --stringparam filename $* poetry.html.deps.xsl $< > $@

# Catch-all
%.mk:
        touch $@

#### Output ####

%.toc %.log %.aux: %.latex
        latex $*.latex

%.dvi: %.latex %.toc
        latex $*.latex

%.ps: %.dvi
        dvips -o $@ $<
-----{/Makefile}-----

That is, auto-calculate dependencies for making a target when one knows
that that target may have to be made. This can not be replaced with a
static rule to calculate all automatic dependencies, as that would be
way too much in some cases (%.texml: %.xml %.texml.deps in the above
code matches _many_ files).

Is it possible to have make re-start the current run with a new make-
file, similarly to "exec" in the shell?
